Testimonials

Big thanks to my friend Oke Millett for sourcing and custom cutting the stone......
I got to whip up a little something for my father-in-law... it’s his design, a man’s ring (with a LOT of bling). Two-tone solid gold, and a BIG custom cut yellow sapphire. Big thanks to my friend Oke Millett for sourcing and custom cutting the stone, and designing the “cheat” tension mounting. Pretty cool!
